kevinayP Posted May 18, 2010 Report Share Posted May 18, 2010 Hello,for P2 TZ2, who remembers the polarizer question and the graph that they asked you to sketch?I still remember that question. =DSo what was the graph supposed to be like? I don't remember the question, I just remember what I sketched for the graph which I think is wrong... I think the graph I did was wrong too... I did an absolute cosine curve. Something like this.I did the same thing, and yes, it was wrong... What's the right graph like? If it's a cos^2 graph, then the overall shape of the graph isn't really much different from the absolute cosine curve... Reply Link to post Share on other sites More sharing options...
hanniexx Posted May 18, 2010 Report Share Posted May 18, 2010 I think the graph I did was wrong too... I did an absolute cosine curve. Something like this.I did the same thing, and yes, it was wrong... Ah...I did that, but my lines were straight. Oops. I might get like 1 mark. If I recall, it was 2.It's probably 1 mark for the curve, and 1 mark for starting near the top, at 1, then half way coming to 0 on the x-axis. Probs...hopefully.

If it's a cos^2 graph, then the overall shape of the graph isn't really much different from the absolute cosine curve...There aren't any sharp edges in the cos^2 graph and the curve is very slightly different (cos^2 curve is slightly lower than cos curve but I doubt the examiners will take note of this since it's just a sketch). I guess you can hope that the examiner doesn't notice your mistake Reply Link to post Share on other sites More sharing options...

wys Posted May 18, 2010 Report Share Posted May 18, 2010 OH NO. for the 'give a method other than the michelson experiment' questoin. I TALKED ABOUT THE MICHELSON EXPERIMENT !!!!. I got the name mixed up with another experiment's. All marks gone there.....? Reply Link to post Share on other sites More sharing options...

All marks gone there.....?same here. but it is only 2 points. so you are good.My answers were even more stupid - I explained about the Muon experiment, which has nothing to do with the question, if I remember correctly. Thank god it's only 2 points. Reply Link to post Share on other sites More sharing options...

They DO have the formula for intensity of the polarizers and stuff in the formula book... its cosine^2 graph (or i'm just trying to reassure myself lol) Reply Link to post Share on other sites More sharing options...
